8) If a cube is cut by a plane to form a cross section, under what circumstance can the cross section
be a non-rectangular parallelogram?
Answers
a) when the plane cuts three faces of the cube, separating one corner from the others
b) when the plane passes through a pair of vertices that do not share a common face
c) when the plane is perpendicular to the base and intersects two adjacent vertical faces
d) when the plane makes an acute angle to the base and intersects three vertical faces
e) not enough information to answer the question
The right answer is the first choice: a) when the plane cuts three faces of the cube, separating one corner from the others
You can see a picture of this case in the figure attached: as you can see the cross section (in pink) is a triangle.

Help Please!!! And can you explain how you got the answer?
Answers
Answer:
x=25
y= 64.5
Step-by-step explanation:
When lines are parallel, 2x=2(the number)
But, 2 isn't an angle. However, 50degrees is congruent to 2 since they are verticle angles.
2x=50
x=25
When lines are parallel, 2y+1=1(the number)
But, 1 doesn't have a verticle angle. However, 180-50 would be equal to 1
180-50=2y+1
130=2y+1
129=2y
y= 64.5

find all the real and complex zeros of f(x)=x^3-7x^2+4x-28
Answers
Answer:
For [tex]x \in\mathbb{C}[/tex]
[tex]x = -2i[/tex]
[tex]x = 2i[/tex]
[tex]x = 7[/tex]
Step-by-step explanation:
[tex]f(x)=x^3-7x^2+4x-28[/tex]
For [tex]f(x) = 0[/tex]
[tex]x^3-7x^2+4x-28 = 0[/tex]
We can easily factor the expression [tex]x^3-7x^2+4x-28[/tex] by grouping.
[tex]x^3-7x^2+4x-28 = (x^3-7x^2)+(4x-28) = x^2(x-7)+4(x-7) = \boxed{(x^2+4)(x-7) }[/tex]
Now we have
[tex](x^2+4)(x-7) = 0[/tex]
Therefore,
[tex]x^2+4 = 0 \text{ or } x-7 = 0[/tex]
So,
[tex]x^2 = -4 \implies x = \pm\sqrt{-4}[/tex]
Once [tex]\sqrt{-1} = i[/tex]
[tex]x = \pm\sqrt{-4} = \pm\sqrt{4}\sqrt{-1} = \pm 2i[/tex]
